In its Climate Change Strategy published in 2010 the Welsh Government set out its target of reducing greenhouse gases in Wales by three per cent year-on-year, and at least a 40 per cent reduction by 2020.

The Committee was given three reasons for the failure - the European Union Emissions Trading Scheme, the economic make-up of Wales and weather patterns.

But the Committee concluded that these variables should have been taken into account when the policies were developed and targets set.

The Welsh Government is being advised on its new approach, framed by the Environment (Wales) Act 2016, by the UK Committee on Climate Change, which has recommended it set new, lower targets in the short term.

The Assembly committee believes this is regrettable but necessary given the lack of progress by the Welsh Government.

Members also learned that the level of engagement in the Welsh Government’s Cabinet on climate change was insufficient, with a lack of joint-working across different departments.

Even though the European Union Emissions Trading Scheme may be a reason for missing emissions targets, the Committee notes there is still no sign of a new scheme to take its place after the UK leaves the EU. The Committee concludes there needs to be a greater sense of urgency on addressing this matter.

“That the Government will miss these targets by some margin is deeply disappointing, and the Committee is not convinced by some of the reasoning behind the failure.

“We believe there needs to be a much more co-ordinated approach across government departments if Wales is to truly become a greener, more sustainable nation.

“In the short term we accept the view of the Committee on Climate Change that the Welsh Government revise down its targets.

“We have made a number of recommendations in our report around agriculture, forestry, housing and transport which we believe will ensure ministers will deliver on their climate change commitments and obligations.”
